How is the insulation of vegetable greenhouses applied?

Vegetables are one of the main planting items in my country. As people's requirements for food become more and more strict, the improvement of vegetable quality becomes more and more important. Therefore, pollution-free vegetable cultivation has gradually become the main vegetable cultivation method. Pollution-free cultivation can effectively improve the quality of vegetables and enhance the food stability of vegetables. Pollution-free vegetables are clean, stable, high-quality and nutritious vegetables produced in strict accordance with the pollution-free vegetable production stability standards and cultivation techniques. In addition, the content of pesticide residues, heavy metals, nitrates, nitrites and other substances that are toxic and harmful to the human body in vegetables should be controlled within the legal allowable limits and must comply with relevant standards. With the rapid development of the greenhouse planting industry, vegetable greenhouse insulation has become an indispensable insulation material for greenhouse cultivation friends, and it has become a fortune assistant for greenhouse cultivation and cultivation friends. This is because the current thermal insulation quilt is no longer the thermal insulation material in the traditional sense of the past. Traditional thermal insulation covering materials include straw, mats, paper quilts and old quilts. The common disadvantages of traditional greenhouse insulation materials are that they are bulky, labor-intensive and laborious to roll and unwind. After being wetted by rain and snow, it not only increases the weight, but also reduces the thermal insulation performance, and causes serious pollution to the film, which is easy to reduce the light transmittance. It does not have the functions and advantages of the new vegetable greenhouse insulation quilt, and the vegetable greenhouse insulation quilt is used as the“cotton coat”, While raising the temperature of the greenhouse, it also contributes to enriching people's dining table in winter! The currently developed new-type vegetable greenhouse insulation blanket has made corresponding progress in overcoming the above defects. Vegetable greenhouse thermal insulation quilt has the advantages of strong tensile force, good thermal insulation, small heat transfer coefficient, moderate weight, easy to roll and unwind, good wind resistance, water resistance, and long service life. How is the insulation of vegetable greenhouses applied? 1. Purchase the special roller shutter machine for greenhouse thermal insulation quilt to be used together. Because the thermal insulation quilt is thinner than that of straw, the roller blind machine with a large head cannot be used. There should be a fixed nut every 0.5 meters for the horizontal rolling rod of the rolling shutter machine, so as to facilitate the fixing of the thermal insulation quilt through the steel wire. Prepare sandbags and connecting ropes for pressing the walls on the east and west sides of the greenhouse, and a nylon rope (belt) of the same length for a thermal insulation quilt. 2. The connection between the two beds of the thermal insulation quilt should not be less than 10CM. The nylon rope (belt) under the thermal insulation quilt is fixed on the iron rod of the greenhouse, and the upper end is fixed on the steel wire. Adjust to cover all. After the thermal insulation quilt is installed, there is a connecting rope to connect the overlapping parts of the thermal insulation quilt into one. 3. After the thermal insulation is covered, the east and west walls of the greenhouse should be pressed 30CM, and pressed with sandbags to prevent them from being blown up by the wind and reduce the thermal insulation effect. 4. When the thermal insulation quilt covers the bottom of the greenhouse, the water on the ground should be cleaned up in time to prevent the thermal insulation quilt from being soaked. When conditions permit, place old grass thatch at the junction of the ground and the greenhouse film to prevent the thermal insulation from touching the ground. 5. The thermal insulation quilt is on the back wall of the greenhouse and should be fixed at the center of the top of the wall, so that the top of the wall has a corresponding slope to the north, and is covered with a complete tarpaulin (paper) to facilitate the discharge of rainwater and prevent the thermal insulation quilt from soaking. For farmers, vegetable greenhouse insulation quilt is an important equipment in greenhouse cultivation in winter, and an important material to ensure the temperature in the greenhouse. It is the most contacted by farmers in various types of insulation quilts. Because it has functions such as waterproof, anti-aging and anti-infrared, it also has corresponding requirements for materials. At first, it is made of new materials, and it is not a general new material. It also needs to be able to maintain high temperature functions. In addition, because its use time is also longer. So it needs to be made of a more durable material. There is another type of thermal insulation quilt, which is the cotton felt thermal insulation quilt. As the name suggests, we all know that its main material is cotton felt, and then a waterproof kraft paper is pasted on both sides of the cotton felt. Because we know that these two types of materials are not expensive in the market, the price of this type of insulation quilt is relatively cheap. However, there will be some factors that affect the thermal insulation effect of vegetable greenhouse thermal insulation quilt, no matter what type of thermal insulation quilt is used, if the internal thermal insulation material is selected well, the thermal insulation effect is also very ideal, so this is The main factor! The outer layer of fabric also has an impact on the effect of thermal insulation, because the waterproof and windproof ability of the outer layer of fabric also has a direct impact on the thermal insulation effect of the greenhouse! In addition, a good sewing process should ensure that the lines on the insulation pipe material are beautiful, not bent, not opened, and the needle spacing is uniform. There is also a promotion for the effect of thermal insulation!
